Dream notes and dream rate from scary to dreamy. This will have to be a premium feature, but maybe free...
It's an essential MISSING feature. In the graph tab there should be a button that let you add a description of your dream/nightmare.
Same, since I always seem to forget my dreams within a minute of me waking up. That would be a useful feature to me.
I dream a lot, I think this would be a great feature to have so I can log what I've been dreaming.
